Add a new provider for injecting native libs in android_binary (#18753)
This reverts the changes made recently to AndroidApplicationResourceInfo and moves them to a separate provider. This helps keep the native libs related processing in Starlark separate from resources processing. PiperOrigin-RevId: 485555064 Change-Id: I78725fe022f1e0089f063681b42c857d001165cf (cherry picked from commit e3fae33)
